Wright Map Tutorial – Part 3

In this part of the tutorial, we’ll show how to load ConQuest output to make a CQmodel object and then WrightMaps. We’ll also show how to turn deltas into thresholds. All the example files here are available in the /inst/extdata folder of the github. If you download the latest version of the package, they should be in a folder...

Experimenting With R – Point to Point Mapping With Great Circles

I’ve started doodling again… This time, around maps, looking for recipes that make life easier plotting lines to connect points on maps. The most attractive maps seem to use great circles to connect one point with another, these providing the shortest path between two points when you consider the Earth as a sphere. Here’s one

Accessing global weather model data using the rNOMADS package in R

The rNOMADS package interfaces with the NOAA Operational Model Archive and Distribution System to provide access to 55 operational (i.e. real time and prediction) models describing the state of the ocean and the atmosphere. rNOMADS has been used to get wind and wave data for a real time sailing game, to quantify solar energy available

Updates on Interactive rCrimemap, rBlocks … and the Packt offer!

Testing rCrimemap as a Self-Contained Web Page I've been learning more about rMaps and rCharts since the LondonR meeting. There are many amazing things you can do with rCharts but it does take time to learn all the tweaks. For example, I just discovered that the rMaps objects (like other rCharts ojects) can be...

Aggregating spatial points by clusters

With ubiquitous collection devices (e.g. smartphones), having too much data may become an increasingly common problem for spatial analysts, even with increasingly powerful computers. This is ironic, because a few short decades ago, too little data was a primary constraint. This tutorial builds on the 'Attribute joins' section of the Creating maps in R tutorial to demonstrate how clusters can be...

GSoC Proposal 2014: package bdvis: Biodiversity Data Visualizations

I am applying for Google Summer of Code 2014 again with “Biodiversity Data Visualizations using R” proposal. We are proposing to take package bdvis to next level by adding more functions and making it available through CRAN. I am posting this idea to get feedback and suggestions from Biodiversity Informatics community.
